To all whom it may concern:

Be it known that I, THoMAs CHnIsTorrEL, a citizen of the United States, residing at lvlenomonie, in the county of Dunn and State of Wisconsin, have invented a new and useful lVindow-Frame, of which the following is a specification.

This invention relates to a window frame and a sash removing device.

The sash removing device is secured to the window frame and does not in any way hinder the free movements of the sashes therein nor does it present an unsightly appearance so common in those devices in which projections are employed or resorted to in order to accomplish the aforementioned ends.

A further object is to provide a window frame with a detached portion which is secured to the remaining portion of the frame by the improved sash removing devices whereby the said movable portion or strip may move in a lateral direction, providing for a similar movement of the sash thus freeing it from the stop upon the opposite side of the window frame and allowing both sashes to be drawn forwardly and thus removed from the frame.

The invention further contemplates a sash removing device by means of which the movable strip of the window frame may be moved laterally in a translatory manner, and then rotated providing for the free access to and exposure of the sash cords and weights.

A further object is to provide a window frame in which the sashes are removable, allowing screens or storm sashes to be put on or taken off, or to be inserted in or withdrawn from the window frame from the inside of the room, thus obviating the use of ladders, etc., such as are necessary when the screens are applied from the outside of the building.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of Specification of Letters Patent.

Application filed June 30, 1914. Serial No. 848,242.

the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof, the preferred embodiment of my invention is disclosed.

In said drawings :Figure 1 is a front view of one side of a Window frame illustrating the upper and lower portion of a frame'in section, my improved sash removing devices being shown as secured to a movable strip providing for the ready removal of the window sashes. Fig. 2 is a cross sectional view taken on the line 2-2 of Fig. 1. Fig. 8 is a cross sectional view taken on the line 33 of Fig. 1 and illustrating th movable strip after it has been translated in a lateral manner, allowing for the removal of a sash, and prior to such rotati on as would expose and render accessible the sash cords and weights. Fig. 4 is a rear view in elevation of the sash removing device. Fig. 5 is a cross sectional view taken on the line 5 5 of Fig. 1. Figs. 6 and 7 are perspective views of the latch member and pivoted latch plate, respectively.

Referring to the drawings in which similar reference numerals designate correspondi n g parts throughout the several views, a portion of a window frame is illustrated in the drawings and includes the side 6 and parting strip 7. A window sash 8 illustrated in section in Fig. 2 is adapted to ride between the parting strip and adjacent portions of the frame side in the usual manner. A portion 9 of the side is removed or detached and is referred to as a movable strip and includes a section 10 of the parting strip as illustrated in Fig. 2. The movable strip is cut so as to be of trapezoidal section allowing it to be moved in a lateral direction, (which refers to a direction indicated by the arrow "1 in Fig. 3,) to the rear of the frame but prevents it from moving therein front. The present invention contemplates the provision of the movable strip, and the means vice by means of which it is rotatable and translatably secured to the adjacent portions of the sides of the frame. Inasmuch as each of these devices are exactly similar, only one will be treated in detail it being noted that the structural details as set out for one of the devices applies with equal force to the other.

An angle attaching member 11 is rigidly secured to the portion 11 of the frame side and adj acent the line of division between the frame side and movable strip 9. The angle attaching member, as illustrated in Fig. 5, is countersunk in the front face of the portion 11 and rigidly secured thereto by suitable screws 12. A pivot pin 13 is carried by the angle attaching member and includes an outstanding head 14. A link 15 is provided with the longitudinal slot 16 which receives the said pivot pin therethrough and holds the same against detachment therefrom by the head 14:. The opposite extremity of the link is provided with the apertures 17, through which a pivot 18 extends. The pivot 18 engages the link 15 and rotatably secures the same to the movable strip 9 to whose under surface, it is secured. The latch member 19 is rigidly secured to the movable strip and includes a bed plate 20 through which the holding screws 21 extend. The bed plate includes the outstanding foot 22 which extends beneath the edge of the movable strip and is rigidly secured thereto by suitable means which extend through the apertures 23 therein. The pivot 18 extends through one of the said apertures 23 thus holding the link in contact with the said foot 22 and providing for their relative ro tation.

The bed plate is provided with a number of longitudinally extending slots 2e through Which extend the tongues 25 of the front latch plate 26. The tongues are bent into engagement with the sides of the slots after having passed therethrough thus securingthe bed plate and front latch plate together and holding the same in sliding relation. The bed plate is provided with the longitudinally extending and laterally arranged bulged portion 27, a portion of which is cut away on three sides to form a resilient locking member 28. The locking member is provided with the outstanding and finger engaging portion 30 which also coacts with and is adapted to extend through an aperture 31 in the front latch plate thus locking the latter against movement with respect to the bed plate. In order to guide the resilient locking member and limit its movements, the guiding end 29 is provided and travels in a restricted slot 29 formed in the bed plate. The front latch plate is illustrated in the lower portion of Fig. 1 in a lowered positionthus extending over the portion 11 of the frame side and holding the movable member 9 stationary. The said plate 20 is countersunk within the movable member 9 to such a degree as to bring the front latch plate 26 flush with the surface thereof thus preserving the continuity of the outer surface of the movable member 9 and the adjacent portions 11 of the frame side thus insuring the successful and smooth operations of the window sashes. The trapezoidal contour of the movable member 9 prevents a lateral and what is termed forward movement of the movable member thus coacting with the latch member 19 to hold the movable member stationary.

From the foregoing it will be apparent that each end of the movable strip 9 is capable of oscillating through the instrumentality of the slot 16 and with the coaction of the pin 13 may rotate about the pivot 18 thus allowing the movable strip to move rearwardly and laterally as illustrated by the arrow A in Fig. 3, thus allowing the sash 8 to move a corresponding amount in a corresponding direction. This will free the sash from the opposite side of the window frame and allow the sash to be moved out of the frame. The movable strip may thus translate and rotate to fully expose the sash cords and weights allowing such repairs and replacements to be made as may be necessary to maintain the window in proper condition. From the foregoing it will be apparent that with the window frame as thus constructed, screens or storm sashes may be applied to or removed from the window frame, from the interior of the building, by first removing the window sashes and leaving the window frame opening entirely unobstructed. This is of importance as it does away with the labor necessary to apply the screens from the outside of the window and renders unnecessary the usual holding means employed with the same.

Having thus described my invention, what I claim as new is 1. A window frame including a side and a detached strip, and means engaging the said detached strip and adjacent portions of the frame side mounting said strip for lateral translatory and rotary movements.

2. A window frame including a side and a detached strip, means engaging the said detached strip and adjacent portions of the frame side and mounting said strip for lateral translatory and rotary movements, and means for locking said detached strip in position with its front surface substantially coplanar with the adjacent surfaces of the frame side.

3. An apparatus of the class described comprising an angle attaching member, a headed pin carried thereby, a slotted link detachably secured to said headed pin by 1,135,662 lttt means of said slot, and a latch member in- In testimony that I claim the foregoing as eluding an outstanding foot pivoted to the my own, I have hereto afiixed my signature remote end of said link, said latch member in the presence of tWo Witnesses. including a bed and a slidable plate carried THOMAS CHRISTOFF EL. thereby and means coacting With said bed WVitnesses:

and plate to lock the same against relative ANDREW CARLsoM,
